Abstract

The invention relates to a high-speed gear with oil lubrication, with oil-recycling ducts (8) leading out of the labyrinth chambers of contactless shaft seals (6) to the crankcase (5) of the gear casing (3). According to the invention, the oil-recycling ducts (8) terminate in regions (10) in which a vacuum is automatically established during running operation, independently of the direction of rotation of the gear.

Description

With oil lubrication, especially for the high speed transmission case that is contained in the traction electric machine in the housing
The present invention relates to a kind of with oil lubrication, especially for the high speed transmission case that is contained in the traction electric machine in the housing, wherein the oil sump of mechanism housing is led in oil return from the labyrinth seal chamber of non-contact shaft sealer.
Usually the lubrication system of Modern High-Speed traction electric machine based on, gearwheel is got oil by the submerged lubrication mode by means of its tooth from the oil sump of mechanism housing when starting, and makes driver pinion wetting.Since along with the increase of rotating speed oil content is split produce thin, be distributed in the gas mixture in the whole transmission case, thereby also give the bearing portion fuel feeding of the live axle in the mechanism housing.
The non-contact shaft sealer place of this bearing reliable, do not have wearing and tearing and externally oil, hermetic seal are big problems for the drive unit that has the gearwheel that runs up completely.Usually adopt labyrinth-type excluder, its function is based upon on the basis of slit pressure throttling.The mist of oil of condensation is constantly separated from the chamber, labyrinth of seal arrangement by a siphonic system there, and be back to by the oil returning tube in the loop in the mechanism housing of sealing, should prevent that thus the dirt discharge side of a large amount of leakage of oils by the outside of labyrinth gland from outwards flowing out.The return flow line has a gradient and feeds the top of oil sump for this reason.
Occur such phenomenon in the transmission case of very fast turn-around: gas mixture is as angular velocity mechanism housing in the accompany movement of so-called drag flow to approach gearwheel, and, therefore make labyrinth gland be subjected to limitting big load because internal friction produces very big heat and expansion.This just requires special oil return from the chamber, labyrinth of seal arrangement swimmingly, oozes out to prevent oil.
For the frictional heat with mist of oil is reduced to the degree that can bear, must makes every effort to make the viscosity of interior oil mass of mechanism housing and gas mixture as far as possible little, and in mechanism housing, create glitch-free as far as possible flow characteristic in addition.Necessary on the other hand the assurance, transmission case in no case allows dried running, otherwise can kill, and therefore can not be lower than indispensable oil mass in order to move reliably, causes very little pasta fluctuation tolerance thus, must monitor reliably it.
Therefore particularly for traction electric machine, but also such task has been proposed for the transmission case that runs up that can be used for other occasions, improve the discharge of oil from gap sealing device, to avoid leakage of oil fully, cause as far as possible reliably, that is to say that pasta sensitive and positional deviation shows, and the flow characteristic in the mechanism housing is not had big interference.
Solve according to the feature of this task of the present invention by defined in claim 1 and 8.Subsidiary dependent claims has been stipulated good Mechanical Builds.
Produce a negative pressure by the Bei Nuli effect of utilization of the present invention in the transmission case of running in the ingress of return tube, it supports oil to flow out from the chamber, labyrinth of non-contact shaft sealer effectively.Less than at the static or static pressure in the streaming flow at a slow speed, and current difference is big more according to the static pressure of Bei Nuli principle in quick streaming flow, and static pressure is more little.That is to say that artificially the zone that has drag flow to flow through with mechanism housing narrows down, thereby make the speed of raising drag flow in this zone, descend with respect to the whole system static pressure at this position.If the return flow line feeds this zone, in oil returning tube, form suction at run duration so, the oil that it helps condensation in sealing system significantly flows out.Therefore described structure works to be similar to nozzle in the venturi physically, although it is the purpose that is used for other.Narrow positions is suitable for being placed in the zone that occurs the drag flow top speed in the mechanism housing, just near the gearwheel cylindrical.Specially suitable position under the situation that makes full use of the oil returning tube slope near oil sump above.If cause narrow positions by the thickening of mechanism housing wall material in this zone, its while hole that can also preferably be used for holding the oil returning tube that is used for gearwheel bearing so.Material thickening is preferably made like this, makes cross section two sense of rotation drag flow change and can not form vortex to the greatest extent.In this external another hole near its next door setting a buoy can also be installed, it can be seen by window glass, to read liquid level height.The buoy of this layout also helps in the thin thickened area of housing: no matter still do not disturb the flow characteristic of gas mixture in other sensitive zones of flowing in narrow positions; Next has cancelled generally commonly used, that expense is high buoy pipeline.No matter whether,, then can read the fuel head in this zone in a kind of preferred improvement structure of the present invention if this zone coincides with the face center of gravity of the oil sump liquid level that allows for example because the road surface tilts to make mechanism housing be in heeling condition.Especially the return tube that feeds here provides enough big oil mass for the buoy of transmission case when static.
In order to utilize the discharge suction effect of oil from the bearing of driver pinion, it is in the zone that narrows down that its oil returning tube can feed the people equally.
Expense and locational requirement by the structure of transmission case of the present invention are little of ignoring, and it is processed also without a doubt.This device proper service free also never needs external energy.Except utilizing buoy in some cases so that pasta observe more clear outside, never need the movement parts of machinery.Other useful structures obtain from dependent claims.
By means of an embodiment the present invention is done more detailed explanation.In appended figure, represent
Fig. 1: analysing and observe by the A-A in the gearwheel axis plane of Fig. 3 by the traction electric machine mechanism housing,
Fig. 2: the B-B in the pasta gravity plane that is parallel to cross section A-A by Fig. 3 analyses and observe,
Fig. 3: the side view axially of mechanism housing.
With 1 gearwheel of representing traction electric machine, it is driven by a small gear that does not draw in detail in Fig. 1 and 2.Gearwheel 1 is connected with a canine tooth wheel body 2 screws, and the gearwheel body heat is pressed on the axle that does not draw in detail of locomotive.Represent that with 3 mechanism housing 1 gearwheel 1 and driver pinion are bearing in this housing by means of roller bearing 4.With an oil sump 5 sealings, this oil sump dress is irritated the gear compound graduation circle place of working oil to about gearwheel 1 below the mechanism housing 3.Sealing between mechanism housing 3 and the canine tooth wheel body 2 is carried out by means of labyrinth gland 6.This noncontact seam seal arrangement allows higher relative velocity, does not does not wear and tear in principle.Yet owing to can't avoid the leakage of oil of labyrinth gland 6 fully at high speed rotating formation mist of oil in service pressure, so leach the oil of leakage by a siphonic system 7, and in by the loop of oil returning tube 8, almost completely feed back in the oil sump 5.Have only minute quantity, no longer the oil in the loop and the build up of dirt particle that comes from the outside are discharged by outside dirt discharge side 9 together.
Mechanism housing 3 has the profile of a fluid technique the best, shown in dotted line among Fig. 1 and 2.This profile allows not have friction and does not have eddy current ground and drives drag flow, and drag flow is made up of gas mixture, therefore no longer causes the overheated of mist of oil.But the profile design of mechanism housing 3 sidewalls becomes like this in the minimum gear of gearwheel 1 and tooth root zone, and it is the narrowest by regional 10 that it is become.Shell body wall thickening continuously in this wise for this reason makes the inwall vertical stretching of in the peak region of material thickening mechanism housing 3 under oil sump 5, forms the narrow positions of wishing thus in the following crown district of gearwheel tooth root.The oil return of gearwheel 8 realizes that by the upright opening 8b that a cross-drilled hole 8a and who leads to siphonic system 7 is attached thereto their processing is in the material thickening position of shell body wall.Upright opening 8b feeds in the peak region of material thickening in gearwheel 1 bottom gear teeth region height, just just in time in zone 10, in this zone when transmission case turn round no matter to which direction rotate all set up one for the whole system in the mechanism housing 3 that seals bigger negative pressure.This negative pressure causes a pumping action, and it adds strong leakage oil significantly from the chamber, labyrinth of seal arrangement 6 or the discharge the siphonic system 7.Because pumping action almost no longer includes the transmission case oil leakage and goes out, this has alleviated environmental pressure and has guaranteed has constant oil mass in the mechanism housing 3 in long-time.
Particularly the latter is extremely important for the working life of transmission case, because must be in the transmission case that runs up with the least possible oil mass operation, so that thereby the viscosity of the gas mixture that forms also has its easy radiation to keep as far as possible little, and the unlikely on the other hand transmission case that makes because of oil starvation damages.Therefore controlling pasta and flow characteristic is not had interference effect exactly for high-speed driving is another necessary condition.
Fig. 2 and 3 has pointed out an embodiment for this reason.Front and back near the thick peak value of material are provided with a vertical buoy hole 11 in the wall of mechanism housing 3 in view of the above, are communicated with oil sump 5 below it, intersect with a horizontal hole 12 above, and horizontal hole is to external application one window glass capsulation.Bring up on mechanism housing 3 and oil sump 5 seams by means of buoy 14 height of observation, its pasta of making peace greatly overlaps, do not need other additional parts, these parts make pasta show the cost raising or cause other interference effects in the mobile sensitive volumes of transmission case inner chamber.
As by Fig. 3 finding, the area center of gravity of pasta and the place that pasta shows overlap in good improvement structure of the present invention, thus can be fully and mechanism housing 3 heeling condition that may occur irrespectively see pasta.
Secondly can be seen very well by Fig. 3 that the oil returning tube 15 of pinion bearing 16 also leads within the mobile narrow zone 10 under the gearwheel bearing 17, oil also utilizes the sucking-off from pinion bearing 16 of Bei Nuli effect thus.
